HTML entity symbols are used to implement reserved characters or to express some common characters that cannot be input by the keyboard. The default character set in most browsers is ISO-8859-1. HTML entity symbols are often used in web design.

For example:

字符 实体名称 实体编号  描述
&   &   &   and符号,与
"   "  "   引号
©   ©  ©  版权标志
®   ®   »  注册标志
™   ™ ™  商标标志
“   “ “  左双引号
”   ” ”  右双引号
‘   ‘ ‘  做单引号
’   ’ ’  右单引号

Due to work needs, I wrote a class for converting HTML entity numbers and non-ASCII strings. The code is as follows:

HtmlEntitie .class.php

<?php/**
 *  HTML实体编号与非ASCII字符串相互转换类
 *  Date:   2016-09-07
 *  Author: fdipzone
 *  Ver:    1.0
 *
 *  Func:
 *  public  encode 字符串转为HTML实体编号
 *  public  decode HTML实体编号转为字符串
 *  private _convertToHtmlEntities 转换为HTML实体编号处理
 */class HtmlEntitie{ // class start
    public static $_encoding = &#39;UTF-8&#39;;    /**
     * 字符串转为HTML实体编号
     * @param  String $str      字符串
     * @param  String $encoding 编码
     * @return String
     */
    public static function encode($str, $encoding=&#39;UTF-8&#39;){
        self::$_encoding = $encoding;        return preg_replace_callback(&#39;|[^\x00-\x7F]+|&#39;, array(__CLASS__, &#39;_convertToHtmlEntities&#39;), $str);
    }    /**
     * HTML实体编号转为字符串
     * @param  String $str      HTML实体编号字符串
     * @param  String $encoding 编码
     * @return String
     */
    public static function decode($str, $encoding=&#39;UTF-8&#39;){
        return html_entity_decode($str, null, $encoding);
    }    /**
     * 转换为HTML实体编号处理
     * @param Mixed  $data 待处理的数据
     * @param String
     */
    private static function _convertToHtmlEntities($data){
        if(is_array($data)){            $chars = str_split(iconv(self::$_encoding, &#39;UCS-2BE&#39;, $data[0]), 2);            $chars = array_map(array(__CLASS__, __FUNCTION__), $chars);            return implode("", $chars);
        }else{            $code = hexdec(sprintf("%02s%02s;", dechex(ord($data {0})), dechex(ord($data {1})) ));            return sprintf("&#%s;", $code);
        }
    }
} // class end?>

Output:
